Naturally occurring enzymes are critical to the healthy functioning of our bodies. We produce upwards of 3,000 types of enzymes, which contribute to the construction, maintenance, and repair of every cell in the body.

In essence, enzymes are chemicals that serve as catalysts for various crucial biological functions, like digesting food, healing wounds, and controlling inflammation. However, our bodies don’t always produce all the ones we need, and as we age, we produce lower quantities of enzymes. That’s where systemic enzymes come in.

What Are Systemic Enzymes?

So, what are systemic enzymes, exactly, and what are the systemic enzyme benefits? Systemic enzymes are a type of dietary supplement designed to help the body function properly. When taken orally, proteolytic enzymes (such as bromelain, papain, and protease) can help prevent, control, and reduce some symptoms of aging and various diseases.

What Are the Benefits of Systemic Enzymes?

Scientists have been studying the beneficial effects of systemic enzymes for decades. Here are some of the known medical advantages of taking this dietary enzyme supplement.

Systemic Enzymes Fight Inflammation

Enzymes have natural inflammation-fighting properties. When our bodies are wounded, inflammation is a natural response that helps us comprehend that we’re injured so we take action to help ourselves.

However, chronic inflammation (or inflammation that doesn’t respond to treatment) can be a self-perpetuating problem. The natural role of enzymes within the body is to help reduce and eliminate that inflammation.

For this reason, taking systemic enzymes as a dietary supplement can help speed up healing and make up for any shortcomings in enzymatic production. For instance, the proteolytic enzyme known as papain, which is derived from the papaya fruit, has a clinically proven effect of expediting wound healing.

Systemic Enzymes Can Treat Inflammatory Conditions

Doctors have also long known that systemic enzymes can be used to treat the symptoms of chronic inflammation like osteoarthritis. Bromelain is particularly effective at this task. Derived from pineapples, the natural proteolytic enzyme is considered safe for most patients. Many dietary supplements combine bromelain and papain with other enzymes to form a safe and effective treatment.

Additionally, enzymes may be able to reduce the symptoms of irritable bowel syndrome and Crohn’s disease. And even for those who don’t suffer from a chronic condition, a mild dietary supplement of systemic enzymes has been shown to reduce gas and bloating, especially after meals.

Systemic Enzymes Reduce Fibrosis

As we age, our bodies develop scars both large and small. Scar tissue, known as fibrosis, can have many negative effects on the body. For one, organs can become less efficient when they get clogged with fibrosis, and in severe cases, the scar tissue can cause terminal conditions like cystic fibrosis.

The bloodstream can also become clogged with what’s known as fibrin, the excess debris created by the natural cell-shedding process. While our livers are primarily responsible for clearing out fibrin from the blood vessels, they can become less efficient with age.

Proteolytic means “protein eating.” And since fibrin and fibrosis are primarily made of proteins, proteolytic enzymes are very good at reducing them in the body. Systemic enzyme supplements can help counteract the symptoms of uterine fibroids as well.

Clearing excess fibrin from the body can help the immune system operate more efficiently. Specifically, removing excess fibrin from white blood cell receptors allows them to work at full capacity.

Additionally, it can minimize the risk of strokes and heart attacks by reducing the likelihood of blood clots. As such, people experiencing heart disease often take systemic enzymes to clean out and thin their blood.

Systemic Enzymes Help Digestion

Systemic enzymes are commonly used to help people struggling with digestive issues. But even in otherwise healthy people, taking a dietary supplement of proteolytic enzymes with meals can have many beneficial effects, as they help the body absorb nutrients and proteins while easing the discomforts often associated with digestion.

Controlled studies have shown that people who might normally experience gas, bloating, and feelings of fullness after eating may see a reduction in symptoms by taking systemic enzymes with meals.

Systemic Enzymes Can Help Treat Pancreatic Insufficiency

Digestive enzymes, which are naturally produced by the pancreas, play a central role in turning food into energy. When someone has a condition that causes a reduced output of these digestive enzymes, it’s referred to as pancreatic insufficiency.

One of the leading causes of pancreatic insufficiency is cystic fibrosis. The condition occurs when harmful scar tissue forms in the pancreas and interferes with pancreatic function. Cystic fibrosis can be incredibly painful and lead to weight loss or even malnutrition in patients that can no longer efficiently digest food.

Systemic enzyme therapy can be used to treat pancreatic insufficiency through the administration of dietary supplements like bromelain, papain, and other enzymes. When taken with meals, these enzymes help stimulate the body’s natural digestive processes.

Systemic Enzymes Therapy Can Help Fight Cancer

Many cancers have an immunosuppressive effect that reduces the body’s natural disease-fighting mechanisms. Systemic enzyme supplements have been shown to counteract the immunosuppressive effects of certain types of cancers.

Some enzymes have been shown in laboratory studies to kill cancers outright. In fact, physicians sometimes inject proteolytic enzymes directly into tumor sites to help kill cancer cells.

Lots of folks take systemic enzymes as a prophylactic against cancer. And while wide-scale clinical trials haven’t been conducted to test their efficacy in preventing cancer, many practitioners agree cleansing the body of excess fibrin can help improve immune system function, which is crucial in the fight against cancer.

Systemic Enzymes Promote Wound Healing

Systemic enzymes have been clinically proven to speed up the rate at which wounds heal. Animal studies found that bromelain and papain accelerate wound healing when applied topically to the skin.

Another study of bromelain demonstrated that a 5-milligram dose taken orally sped up the healing process for people recovering from cosmetic surgery. A similar trial showed that the enzyme serrapeptase accelerated healing in patients recovering from dental surgery.

Proteolytic enzymes may also help reduce exercise-related muscle soreness. Several placebo-controlled studies have demonstrated that post-workout muscle soreness can be greatly reduced with bromelain and curcumin. 

Systemic Enzymes are Safe and Non-toxic

Systemic enzymes are generally recognized as safe, non-toxic substances. There is currently no known lethal dose, and in fact, the worst symptom of a very high dose of systemic enzymes tends to be nausea.

Bear in mind that some enzymes are known to have blood-thinning effects. Bromelain, for example, helps cleanse the blood vessels of excess fibrin, which has the effect of thinning the blood. So, anyone taking a blood-thinner should consult with their healthcare provider before beginning a proteolytic enzyme regimen.

Also, known allergies should be an important consideration for anyone looking to supplement their diets with proteolytic enzymes. Most are derived from plants, fruits, animals, and fungi. So those allergic to pineapples, for instance, could be allergic to bromelain. An allergic reaction to proteolytic enzyme supplements may cause a mild skin rash.
